USE OF NON-GAAP FINANCIAL INFORMATION: In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, Symantec reports non-GAAP financial results. Non-GAAP net income and earnings per share exclude acquisition related charges, such as amortization of other intangibles and in-process research and development, and certain other identified charges, such as restructuring and patent settlement, as well as the tax effect of these items. Symantec's management believes these non-GAAP measures are useful to investors because they provide supplemental information that facilitates comparisons to prior periods. Management uses these non-GAAP measures to evaluate its financial results, develop budgets and manage expenditures. The method Symantec uses to produce non-GAAP results is not computed according to GAAP, is likely to differ from the methods used by other companies and should not be regarded as a replacement for corresponding GAAP measures. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to the comparable GAAP results, which is attached to this release and can also be found on the investor relations Web site at www.symantec.com/invest.
